FLORENZ KEISER, OF POTTSTOWN PENNSYLVANIA, ASSIGNQR OF ONE- HALF TO GEORGE J. FELKER, OF SAME PLACE.

CAR-AXLE BOX.

SPECIFICATION forming part of Letters Patent No. 257,720, dated May 9, 1882.

,Applioation filed August 19, 1881. (No model.)

To all whom it may concern Be it known that I, FLORENZ Karma, :1 citizen ofthe United States, residing at Pottstown,

Montgomery county, Pennsylvania, have invented certain Improvements in Axle-Boxes, of which the following is a specification.

Myinvention relates to an improvement in that class of axle-boxes in which the lid swings laterally across the face of the box, the object of my invention being to so construct and hang a lid that it can be readily opened, will be selfretaining in its opened position, will close antomatically when a shaking or jarring movement is imparted to the box, and when closed will effectually prevent the entrance of dust to the interior of the box.

In the accompanying drawings, Figure 1 is a perspective view of my improved axle-box with the lid closed; Fig. 2, the same with the lid opened; Fig. 3, a longitudinal section of the box on a larger scale; and Figs. 4 and 5, front views of the box, showing the method of hang-H ing the lid and retaining the same when elevated. Y

A is the casing of the box, having in front the usual opening, "a, through whichaecess is bad to the interior, this opening being closed by a lid, B, pivoted to the upper corner of the box and adapted to swing laterally across the face of the same, the pivot-bolt passing through a lug, b, on the box, and having in the rear of said lug a nut, preferably adapted to a recess in the top otithc box, so as to prevent it from turning. The lower edge of the lid B is beveled, and is adapted to a beveled projection, d, on the box, as shown in Fig. 3, so as to form a tight-joint, and on the upper edge of the lid is a recessed projection, c, which, when the said lid is depressed, receives the rib fon the upper front edgeof the box A, thereby holding the lid firmly against the front of the box andpreventing the entrance of dust or dirt to the interior of the same. The end a of the projection e serves, by contact with the lug b, to limit the movement of the lid B in the direction of the arrow, Fig. 5, and this stop is so arranged that when the lid is fully opened there will be a slight preponderance of weight on one side, to, of a dotted line, y, drawn vertically through the center of the pivot-bolt,-so that the tendency of the lid when opened will be to remain open. The preponderance of weight on the side to of the line y is very slight, however,-and when the car begins to move a little shaking of the lid is sufficient to so jerk the lid that the preponderance will be on the opposite side, 20, ot' the line y, in which case the lid will instantly fall, its weight in falling causing the lid to be wedged in its beveled seat.

Instead of forming a beveled projection, 11, on the box A, as shown, an L-shaped projection may be inade thereon for the reception of a rib on the edge of the lid.

I am aware that an axle-box lid has been hinged to the box at one side of the opening a; but in this case the width of the opening is contracted, the casing of the box at the side of the opening a being necessarily wider than in my improved box in order to provide a hingelug of proper strength.

I claim as my invention- 1. The combination of the box A and lug b on. the top of the same, near one side, with the lid B, hung at oneof its upper corners to'the said lug I), and having a stop, w, for limiting its movement and maintaining it in a balanced position when opened, as set forth.

2. The combination of the box A, having a rib,j', on its upper front edge, with the laterally-swinging lid B, having on its upper edge a recessed projection, e, as set forth.

In testimony whereoflhave signed my name to this specification in the presence of two subscribing witnesses.
